MOLD WITH SEVERAL MOLDING SECTIONS Russian patent published in 1997 - IPC

FIELD: equipment for manufacture of building products from concrete mixes, particular, multiple molds for manufacture of tiles from sand-concrete mix by casting technology. SUBSTANCE: manufacture of tiles in the offered mold is carried out as follows. Assembled mold is delivered to molding station, where the space between separating partitions is filled with cement-sand mortar by means of hose. Filled mold is held until the mortar attains stripping strength, then, longitudinal sides of mold are opened, fixing members are removed, screws are unscrewed until brackets turn under gravity on their axles through 90 deg, and end sides are withdrawn. For this purpose, end side is lifted to take up the gap between pins of final gathering member and bottom plate, and it is displaced to removable side. End side is installed on bottom plate and inclined to make pins of final gathering member come in contact with nonmolding surface of bottom plate. After that, extreme products are withdrawn and nearest separating partition is moved to formed space to end side up to contact of plate with bevel of final gathering member, and next product is withdrawn. This operation reverse to the process of mold assembly is carried out until withdrawal of all products from the mold. EFFECT: higher efficiency. 3 dwg
